R&S®TMV9evo and R&S THV9evo DAB+ transmitter
Rohde & Schwarz presents its new DAB+ transmitter platform at IBC. The R&S TMV9evo air-cooled medium-power transmitter (350 W and up) and the R&S THV9evo liquid-cooled high-power transmitter (1.3 kW and up) ensure smooth and reliable operation designed for simplicity and longevity.
The biggest challenges for network operators are the various operating costs: energy costs, costs to ensure service quality, the devices’ limited operating life, and even transmission downtime penalties. DAB+ transmission has never been so easy and yet secure as with the two new transmitters R&S TMV9evo and R&S THV9evo. They offer both the lowest total cost of ownership (TCO) and a high safety of investment.
The new DAB+ transmitter platform is characterized by efficient operation at all levels. It is based on a tried-and-tested platform, thousands of which are in use worldwide and proving their reliability day in and day out. Rohde & Schwarz continues to put priority on ensuring the new transmitters a long product life of 15 years or more, thus offering network operators a longer-than-average investment profit phase. Backed up by service level agreements with a term of up to ten years, this ensures constant operational readiness while facilitating planning of operating costs.
The new R&S TMV9evo and R&S THV9evo transmitters feature an outstanding VHF band III amplifier design, providing network operators an extremely high energy efficiency of up to 49 percent in each of the band’s channels. This reduces energy consumption while making operation very cost-efficient. Rohde & Schwarz can draw on years of experience with Doherty technology to achieve exceptional Doherty efficiency. The DAB+ amplifiers also have such a solid thermal design that even continuous operation at 45 °C outdoor temperature and full output power does not limit operation. Rohde & Schwarz DAB+ transmitters ensure broadcasting distribution and reliable operation even under adverse environmental conditions.
With the R&S TMV9evo and R&S THV9evo, the latest features of the recently introduced R&S Tx9evo transmitter platform are now also available for VHF band III. For example, excellent adaptive digital precorrection from Rohde & Schwarz ensures consistently high signal quality over years of broadcasting operation. R&S efficiency optimization is another new feature. It ensures maximum energy savings even after adjusting the output power or changing channels: an intelligent algorithm, which is activated at the press of a button or adaptively, optimizes the amplifier parameters so that the transmitter operates at maximum energy efficiency. Until now, transmitter experts were needed for this purpose, in order to adjust the station’s transmitter to its new parameters. Today, R&S efficiency optimization does this at the touch of a button – even via remote control, thus ensuring the most cost-efficient system operation at all times.
Simple and problem-free transmitter operation is achieved thanks to clear diagnostic information and a high degree of automation. The new R&S TMV9evo and R&S THV9evo DAB+ transmitters are equipped with the functions this requires. The integrated performance analysis gives operators instant feedback on key operating parameters such as shoulder attenuation, efficiency, signal quality and more without additional test equipment. This ensures them a quick and comprehensive overview of the current operating status at all times. The detailed definition of the transmitter’s desired operating point also allows continuous monitoring of the transmitter without any complicated special routines of a network management system. This allows DAB+ network operators to set their limits for shoulder attenuation or MER, for example. In doing so, they can be sure that the new DAB+ transmitters continuously remain within these operating parameters, as long as the transmitters do not give off a warning or an alarm signal. This enables both easy operation and maximum operational reliability.
The R&S TMV9evo air-cooled medium-power transmitter and the R&S THV9evo liquid-cooled high-power transmitter for DAB+ are now available from Rohde & Schwarz.
